16.5.4
TCNT is cleared when compare match A or B occurs, depending on the settings of the bits
CCLR1 and CCLR0 in TCR. Figure 16.11 shows the timing of this operation.
16.5.5
TCNT is cleared at the rising edge or high level of an external reset input, depending on the
settings of bits CCLR1 and CCLR0 in TCR. The clear pulse width must be at least 2 states. Figure
16.12 and Figure 16.13 shows the timing of this operation.
Note: * Clearing by an external reset is available only in units 0 and 1.
